+* Microchip I2S Multi-Channel Controller
+
+Required properties:
+- compatible:     Should be "microchip,sam9x60-i2smcc".
+- reg:            Should be the physical base address of the controller and the
+                  length of memory mapped region.
+- interrupts:     Should contain the interrupt for the controller.
+- dmas:           Should be one per channel name listed in the dma-names property,
+                  as described in atmel-dma.txt and dma.txt files.
+- dma-names:      Identifier string for each DMA request line in the dmas property.
+		  Two dmas have to be defined, "tx" and "rx".
+- clocks:         Must contain an entry for each entry in clock-names.
+                  Please refer to clock-bindings.txt.
+- clock-names:    Should be one of each entry matching the clocks phandles list:
+                  - "pclk" (peripheral clock) Required.
+                  - "gclk" (generated clock) Optional (1).
+
+Optional properties:
+- pinctrl-0:      Should specify pin control groups used for this controller.
+- princtrl-names: Should contain only one value - "default".
+
+
+(1) : Only the peripheral clock is required. The generated clock is optional
+      and should be set mostly when Master Mode is required.
+
+Example:
+
+	i2s@f001c000 {
+		compatible = "microchip,sam9x60-i2smcc";
+		reg = <0xf001c000 0x100>;
+		interrupts = <34 IRQ_TYPE_LEVEL_HIGH 7>;
+		dmas = <&dma0
+			(AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) |
+			 AT91_XDMAC_DT_PERID(36))>,
+		       <&dma0
+			(AT91_XDMAC_DT_MEM_IF(0) | AT91_XDMAC_DT_PER_IF(1) |
+			 AT91_XDMAC_DT_PERID(37))>;
+		dma-names = "tx", "rx";
+		clocks = <&i2s_clk>, <&i2s_gclk>;
+		clock-names = "pclk", "gclk";
+		pinctrl-names = "default";
+		pinctrl-0 = <&pinctrl_i2s_default>;
+	};
